change the order and it will work:

        catalog = Catalog()
        tools['catalog'] = catalog
        catalog_reg = UtilityRegistration('catalog', ICatalog, catalog)
        rm.addRegistration(catalog_reg)
        catalog_reg.status = ActiveStatus
        # add the indexes after the catalog is set to the tools
        for index_name, index_attribute, idx_if, attr_call, index_type
in indexes:
            idx = index_type(index_attribute, idx_if, attr_call)
            catalog[index_name] = idx
